ʻOi aku paha ka ʻoi aku o ka ʻoi aku ka maikaʻi ma mua o ka pahu pahu semi-metallic?

Hoʻomohala ʻia ka ʻenehana automotive, ua hoʻomohala ʻia ka mea o nā mea friction ma ke ala āpau, i māhele ʻia i nā ʻāpana nui:

Paʻa kaʻa
Ma mua o ka makahiki 1970, ua nui ka nui o nā mea asbestos i loko o nā pale pale, e lawe i ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa ahi, a me nā ʻano frictional, akā no ka mea ʻo ka pauka i hana ʻia e ka asbestos i ka hana ʻana a me ka hoʻohana ʻana, aia nā ʻano pōʻino i ke kino kanaka. , ka mea maʻalahi e hoʻoulu i nā ʻōnaehana hanu.He carcinogenic nā maʻi, no laila ua pāpā ʻia ka pulupulu e ka honua.
A laila, kapa ʻia nā pad brake organic o kēia manawa he NAO brake pads (Non-Asbestos Organic, ʻaʻohe pōhaku-free organic brake pads), nona ka 10% -30% o nā mea metala, a komo pū kekahi i nā mea kanu, nā aniani Fibers, carbon, ka pulupulu, ke aniani a me na mea e ae.
Ua hoʻomaikaʻi maikaʻi nā pad brake organik i ka hana ʻana i ka ʻaʻahu a me ka hoʻokele walaʻau ma o nā makahiki he nui o ka hoʻomohala ʻana a me ka hoʻomaikaʻi ʻana i nā mea, akā kūpono hoʻi no ka hoʻokele i kēlā me kēia lā.ʻOi aku ka liʻiliʻi o ka lepo i hana ʻia a me ka pōʻino o ka disc brake.Eia nō naʻe, ma muli o ke kumukūʻai waiwai, a me nā mea ʻē aʻe, ʻoi aku ke kumukūʻai o ke kiʻi ʻoniʻoni organik, a e hoʻohana mau ʻia ka hale hana kumu ma nā kumu waena a me nā hiʻohiʻona kiʻekiʻe.

Pākuʻi semi-metal
ʻO ka mea i kapa ʻia ʻo ka hapalua metala ka mea nui i loko o nā mea friction i hoʻohana ʻia i loko o ia mau pahu pahu, mai kahi o 30% -65% o ka metala - me ke keleawe, ka hao, a me nā mea ʻē aʻe. kumu kūʻai haʻahaʻa haʻahaʻa, a ʻo ka hemahema ma muli o nā kumu waiwai, e nui ka walaʻau i ka wā o ke kaʻa, a nui ke kāʻei ʻana o ka mea metala i ka disc brake.No ka loaʻa ʻana o nā hiʻohiʻona o ka semi-metal brake pad i nā hiʻohiʻona o mākou ma luna, aia ka nui o ʻelua mau noi nui, ʻo kekahi ʻo ka hale hana mua e kākoʻo ana i nā pā kīwī o nā kumu waena a me nā hiʻohiʻona haʻahaʻa - ʻo kēia ʻano ke kumu kūʻai haʻahaʻa.ʻO ka ʻaoʻao ʻē aʻe ka mea nui ma ke kahua o ka ʻili ʻili i hoʻololi ʻia - no ka mea, maikaʻi nā mea hao hao, ʻoi aku ka maikaʻi no nā kaʻa hana kiʻekiʻe a i ʻole i nā hanana like ʻole.Ma hope o nā mea a pau, ma kēia ʻano o ka hoʻohana ʻana, e piʻi ka mahana kiʻekiʻe o ka ʻili o ka ʻili ma mua o 800 degere Celsius.No laila hiki iā mākou ke ʻike i ka nui o nā hōʻailona i hoʻololi ʻia i kahi mea metala kiʻekiʻe no nā kaʻa o ka hoʻokele ikaika a me nā hanana.

Pākuʻi pāpaʻi keramika
Hiki ke ho'ākāka 'ia nā pad brake ceramic no ka lawa 'ole no nā pad brake organic a me semi-metal.Hoʻohui nui ʻia kāna mau mea e nā ʻano mea like ʻole e like me nā fiber mineral, nā aramid fibers, a me nā fibers ceramic.Ma ka ʻaoʻao hoʻokahi, inā ʻaʻohe mea metala, ka pahu pahu a me ka disc brake, e hoʻemi nui ʻia ka walaʻau.I ka manawa like, e hoʻemi nui ʻia ka pōʻino o ka disc brake.Eia kekahi, hiki i ka ceramic brake pads ke kūpaʻa i ka wela kiʻekiʻe, e pale aku i nā mea hoʻoheheʻe organik a metala paha ma muli o ka wā lōʻihi a i ʻole ka wikiwiki wikiwiki, ma muli o ka ikaika o ka hoʻoheheʻe ʻana o ka mea, hoʻonui nui i ka palekana.ʻOi aku ka ʻaʻahu.
